What are NoSQL Databases?
NoSQL, also referred to as "not only SQL" or "non-SQL," is a database design technique that enables data to be stored and accessed outside of traditional relational database structures. Although it does it in a different fashion, it can nevertheless store data from relational database management systems (RDBMS). The use case and other environmental factors mostly determine whether to use a relational or non-relational database. NoSQL databases store data in a single data structure, like a JSON document, as opposed to the traditional tabular structure of a relational database. This non-relational database design provides quick scalability to handle big and frequently unstructured data volumes because it is not dependent on a schema. Due to the fact that NoSQL is a sort of distributed database, data is duplicated and stored on numerous servers, some of which may be local or remote. This guarantees the data's accessibility and dependability. The database can still function even if some of the data is unavailable.
